Sexually Transmitted Diseases (STDs)

The term sexually transmitted disease is used to cover the more than 25-30 infectious organisms that are spread through sexual activity. STDs are almost always spread from person to person by sexual activity. These infections are most easily spread by vaginal or anal intercourse, and sometimes by oral sex. Some STDs can also be spread through blood, particularly among intravenous (IV) drug users who may be sharing drug equipment (needles, syringes, or "works"). In addition, pregnant women with STDs may pass their infection to infants in the uterus (womb), during birth, or through breast-feeding.

Most people with STDs have no symptoms. Without treatment these diseases can lead to major health problems such as not being able to get pregnant (infertility), permanent brain damage, heart disease, cancer, and even death. If you think you have been exposed to a sexually transmitted disease, you and your sex partner(s) should visit a health clinic, hospital or doctor for testing and treatment.
